A new method to incorporate qualitative knowledge in semiqualitative
systems is presented. In these systems qualitative knowledge
may be expressed in their parameters, initial conditions and/or vector
fields. The representation of qualitative knowledge is made by means of
intervals, continuous qualitative functions and envelope functions.
A dynamical system is defined by differential equations with qualitative
knowledge. This definition is transformed into a family of dynamical systems.
In this paper the semiqualitative analysis is carried out by means
of constraint satisfaction problems, using interval consistency techniques
